INSERT(3PVM) PVM Version 3.4 INSERT(3PVM)NAMEpvm_insert - store data in pvmd database
[In Version 3.4: Relaced by pvm_putinfo]
SYNOPSIS
C int cc = pvm_insert( char *name, int index, int data )
Fortran Not available
PARAMETERS
name The class name, a null-terminated string.
index The class index, >= 0 or -1 for first available.
data Data to store in the <name, index> entry.
DESCRIPTION
The master pvmd maintains a simple database, which can be used to store
values such as tids and make them accessible anywhere within a virtual
machine. This is useful when building an application such as the group
server, which must advertise its task id so clients can register send
messages to register.
The database stores integer data, indexed by <name, index> pairs. The
name may be any null-terminated string and the index any non-negative
integer. Database entries are grouped by name into classes; index may
be specified as -1 to store or retrieve the first available instance in
a class.
These functions are not part of the group library, but are the underly‐
ing mechanism used to implement it.
pvm_insert stores data at the given index. If index is -1, the data is
stored at the first available index in the named class, starting at 0.
ERRORS
If successful, pvm_insert returns the index at which the data was
stored, otherwise it returns a negative result. The following error
conditions can be returned:
PvmBadParam
giving an invalid argument value.
PvmDupEntry
the requested <name, index> pair is already in use.
